The DDZ33CSF-7 is a precision Zener diode from Diodes Incorporated with a nominal Zener voltage of 31.7V and a tight ±3% tolerance. It is rated for a maximum power dissipation of 500mW on FR-4 PCB, making it suitable for voltage regulation and overvoltage protection in low-power circuits. The device exhibits a maximum impedance of 80Ω at 1kHz and a reverse leakage current of only 70nA at 29.4V. Forward voltage is 900mV maximum at 10mA. The operating temperature range spans -65°C to 150°C, with a thermal resistance of 250°C/W junction-to-ambient.
The DDZ33CSF-7 is housed in a surface-mount SOD-323F package (SC-90), which is ideally suited for automated assembly processes. The package is molded from green compound, is halogen- and antimony-free, and meets UL flammability rating 94V-0. Terminals are matte tin annealed over copper alloy leadframe, solderable per MIL-STD-202 Method 208. The device is fully RoHS3 compliant, lead-free, and has a moisture sensitivity level of 1 (unlimited). Standard packaging is 3,000 pieces on tape and reel.
